IMPROVEMENT IN :Lows.

The Schedule feferred'to in these'Le ttera Patent and making part of the same.

To all whom it may concern Be it known that I, LEWIS T. WEBSTER, of Northfield, in the county of Franklin, and State of Massachusetts, have invented new and useful Improvements in Flows; and I hereby declare that the following is a full and exact description of the construction and operation of the same, reference being bad to the accompanying drawings making part of this specification, in which- Figure 1 is a side view, and

Figure 2, a top view.

Like letters refer to like parts in the several views.

My invention. has four points of novelty: first, the compound and bifurcated tongue and beams; second, the manner of appiyingIt he draft; third, a guide-plate to determine the widthof the furrow and take up the side-draft ofthe plows; and fourth, in the devices for attaching the wheels to the compound tongue and beams, together with the devices for raising the plows from the ground.

The tongue A and beams A A" are composed of one piece, and are divided, as shown in fig. 2, to a point a little forward of the foremost wheel'B, the wheel Bupon the opposite side being placed about half its diameter in the rear.

A round shaft, G,"is secured to the beams A; A" upon the under side by journal-boxes just in rear of 'tlieavheel B, and from the right-hand end of this shaft 0 a, double'arm, D, is rigidly attached,in the forward end of which the wheel-B is journaled.-

To the under side of the beam A is secured the bearing E, which supports the double arm D, to the forward end of which the wheel B is journaled.

- From the left-hand end of the shaft 0 rises the lever G, to which it-is rigidly attached, so that by moving the lever G backward and forward, the arm D and wheel B will be raised or lowered at pleasure.

From thejournaled end of the arlnD', shown at E, rises all-arm, F, which is firmly fixed to the hub E of the arm I). p

A connecting-rod, G, unites the arm 1 and leverO, as shown in fig. '1, thus securing, by the movement of the lever, the simultaneous adjustment of both wheels B and B, by which the depth of the furrow is regulated.

The lever O can be secured at any desired point by a pin inserted therein engaging with notches in the segment H.

To the hub E of the arm I), is also rigidly attached a foot-lever, I, by which the {adjustment of the wheels 'B and}? can-be cflected'- 1 ,Near therein" 'end of the beam Af', in the rear of and above the shaft 0, I attach the crooked arm K,

which carries upon its lower and forward end the furrow-guide L.

This furrow-guide is made of steel-plate or other hard substance, and is so adjusted as to press against the land-side of the last furrow, and is supported in that position by the brace M, which is adjustably at- .tached to the beam A"just at the rear end of the tongue.

The shaft O'is provided with an adjustable collar,-

N, around which the draft-rod 0 passes, the forward end of this rod being attached directly to the doubletree 1 which has no other connection with the plowbeams, and thus, by shifting the collar N on the shaft 0, the draft can be properly adjusted for both plows.

Q represents the track-clearer, which is attached to the beam A" in front of the wheel B.

It is made vertically adjustable by a series of holes at its pivoted attachment, and itis. otherwise regulated by the chain Q, by shortening or lengthening the same.

It will be observedthat the wheel B, in every succeeding round, follows in the track of the wheel B, and thus a single clearer clears the track for both wheels, and the wheel B always runs 'onthe unplowed land.

The plows R R are attached to the rear ends of the beams A A", by bolts passing through flanges upon the upper end of their standards.

The rear ends of the beams are made adjustable by means of ab adjusting-rod S, one, end of which isfastened to the side of the beam A, and the free end passing through lug ,upon the rear end of the beam A and having a screw-thread out upon it and nuts upon each side of the log, the two beams can be adjusted lateral ly to any necessary extent.

The arm K, which carries the furrow-guide, is also made adj ustableby means of a series of bolt-holes, by which it is attached to the beam A".

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-- 1. The compound bifurcated tongue and beams A A A", when constructed as herein set forth.

2. .The draft-rod-O, in combination with the shaft r O and adjustable collar N, as specified.

,3. The guide .L, constructed and arranged as described. 4. The arms D and D, in combination with the wheels 'B and B, and their respective axles, and lifting device 0 F G I, when arranged as specified.
